Expect No Conditions to be Thrown

Expectation predicate for testing that a given function does not raise a condition

expect_no_condition(
  current,
  pattern = NULL,
  class = NULL,
  ...,
  info = NA_character_
)

Arguments

current

[R object or expression] Object or expression to be tested

pattern

[character(1L)] A regular expression to match the condition message; any conditions thrown with a message matching pattern will trigger a failure while all other conditions thrown will trigger a success. Must be a single character string

class

[character] Optional vector of condition classes that should not be thrown; conditions thrown that inherit from class will trigger a failure while all other conditions thrown will trigger a success. If NULL, any condition thrown will trigger a failure

...

Ignored

info

[character(1L)] Optional user-defined message; must be a single string value

Value

A tinytest object. A tinytest object is a logical with attributes holding information about the test that was run
